To all 'whomfit-amycc'lscuev-m:k

Be it known that'I, J ms FOUGH, a citizen oi the United States, residing at .Minneapolialin the. ccuntyof -Hennepin and State o Minnesota, have :invented certain new and useful Improvements' in Metallic Wheels; and I dc hereby declare the following to. bea

full, clear, and exactdescri tion of the invention, auch as enable ot ers skilled 'in the fart' to which` it-appertains to make and-use the same.

lMy invention has for-itsob'ect to rovide an improved metallic Wheel a Aapted magen.

iustrating a mo ed construction of the wheeh4 Describing iirst thel construction illus- .trated in Figs. 1 and 2, the numeral 1 indicates a pair ofV reversely bul ed conical pressed -steel plates which, at t eir central portions, are provided with quite large axial passages, immediately surrounding which the said plates' are formed with conical flanges 2. While these-conical 'lianges may,

` .so far as the broad idea 'of the invention is concerned, be turned either inward-or outl inward.

ward of the rojectedconical surfaces of the.

lates 1, by ar the best results are obtained y tu both of the said conical flanges 2 he outer portions of the two corricalplates lare :brdught together and are de- -tachably, connected by suitable devices, but

preferably by short nutted'bolts' 3, the heads fof iwhich are soldered or brazed toone of the said conical lates so as to revent displacementthereo when the twoponical plates of the wheel are se arated. l @Outward oft e circurnierentially spaced row'ofv nutted bolts 3 the conical plates 1 are'provided with reversely projected tireclamping flanges 4, which together consti-` tute a' separable .peripheral channel-shaped' 55. rimthat 1s adapted to clamp vand hold the ribbed inner portion of a' pneumatic tire 5 of 3 is a view corres ondingA 'standard construction. `.At asuitabl'e point ad'acent -to the-divided rime, one of the conica 'i lates-'I1 is rovided with an approximate y s emitulm4 ar de ression that affords a through whi the valved charging itu (not shown) of the tire may projectinconical flanges 2 of the conical plates 1 closely ts the conicaflflange 2 of the adjacent conical plate 1 and is secured thereto by rivets 9. '-At its other end .the hub 7 is provided 'with a telescopicalily detachable clamping collar -10 which has a conical flange 11, the inner surface of whichclosely :engages the 1*,'and Whli -ilangesr2and 11 are ri 'dly fsecured together by rivets 12. collar 10 is rigidly secured to a flange 13 on the hub 7, as shown, by means of studs 14 throughdperforations in said collar 10 and are provi e surface of said collar. i

When the cooperating relatively fixed and movable flanges 8 and 11 of the hub 7 are tightly drawn against the inwardly bulged conical lianges 2 of the 'conical plates 1,' the hub is centered in respect to the wheel plates, and as the said conical hub flanges are .drawn draw )together e central portions of the reversely bulged conical-wheel plate, but this entire force is resisted-by a straight end or radial thrust on/the said Wheel plates. When that reverselybulged wheel plates of truly conical form will be much more difiicult to buckle than'reyersely bulged wheel plates of ellipticalconcavoconvexforrn. Alsoltwillbe noted that the inwardl turned late flanges 2 dorm the' best ossib e kind o joints wlth the conical hub anges and are best adapted 'to withstand the lateral pressure therefrom. In fact, the joints thus .made are so firm .and that in some instances it `is not neces'- sary to use rivets or btelts to connect the said conical flanges.

The wheel shown in Figs. 1 and 2 has a hub that is adapted to be journaled to an axle, but in some cases, such as for traction Patented Dec. 22, '1908.

are-secured to a hub1 7 that extends through 8 the inner surface of which is conidal,

conical-lla e 2 oi' the adjacent conical plate The c amping that are secured to said flange 13, projectinto the conical `lllate ilanges 2,they tend tothis action is considered it will be evident the axial passage thereof. This hub 7 ,'at pine e1`1d5is provi edwith an integrally formed ange with nuts 15 that engage the outer wheels, where theaxle is driven., these hubs wcfuld'be rigidly secured to or even formed as art of axle. AThe numeral 16 indicates a etachable cap applied to the outer end ofthe hub 7. Y

As is evident, all lthat is necessary in applying a tire the Wheel or in removing a tire therefrom, to iirst remove the nuts of the bolts 3 14 and then remove the collar 10 and connected Wheel plate 1 laterally from Working position. This is an easy o eration and maw17 he ve quickly performe 'i In 'the c suction illustrated -in Fig. 3: the conical e; plates 1 are substantially identical these shown in Figs. 1 and 2, but th ccrticns are s aced apart by an anun ing rim 20 W A, ich, as shown', is cha ed in cross section. Nutted bolts l `d through perforations in the Whe and in the flanges of the spacing n zo and rigidly secure said parts together "I s Wheel hub 22 in this constructioi @vided with conical fla es 23 that e The inner surfaces of the conical iange e Wheel plates 1. Outward of the ila@ .3 the hub is lexternally.

25 threaded a d provided at its inner end with a threaded clam`r ing collar 24 andat its outer with a ti'ireaded clamping collar 25. rlhese damping-collars 24 and 25 have conical surfaces that engage the conical outer surfaces ci the plate lianges 2 and rigidly clamp the same against the coperating hub flan es 23. Y

T e construction shown in Fig. 3 is es eciaull'y Well adapted for use in Wheels t at must withstand heavy loads. A spacing rim 20 adds greatly to thestrength ofv the periphery or rim portion of the Wheel and adapts the Wheel rim to hold very large pneumatic Y' or solid tires; and the hub construction very rigidb`T holds the conical plate ilanges 2 and reinforces the latter.

What I claim is: I In a Wheel, the combination with out.- Wardly bulged conical plates rigidly but detachably secured atA their outer extremities and provided with means for holding a tire, and at their central portions havln inturned conical lianges surrounding aXia ,hub passages, land a hub seated in the hub pas' sages of said plates and providedwith inner 50 and outer conicallianges en aging the inturned conical flanges of said plates. and rigidl;r clamping the'same, substantially as described. l
